Ford Focus ST MK4 2019-2021 Rear Diffuser — the sporty touch that changes everything

Give your Ford Focus ST MK4 (2019, 2020, 2021) a decidedly racing look with this glossy black rear diffuser. Designed for enthusiasts who want a distinctive visual signature, it dresses the lower rear bodywork and accentuates the sporty character of the compact sedan.

A design created for your Ford Focus ST MK4

The vertical fins and glossy black finish blend seamlessly with the original bumper for a cohesive and aggressive look. The diffuser effect visually elongates the car toward the ground and gives it a wider and lower stance.

Design, quality & finish

Made of rigid ABS plastic, this diffuser resists minor impacts, debris, and temperature variations. The glossy black lacquered finish offers a deep shine that pairs with any body color.

Installation, compatibility & durability

Designed to fit the lines of the Focus ST MK4 rear bumper. Installation is done using fasteners and high-strength adhesive; careful installation, preferably by a professional, is recommended for perfect alignment. Compatibility should be checked according to the version before installation.

Give your Focus ST the diffuser look it deserves, order now.

Useful tools

  • Torx screwdriver
  • Socket wrench
  • Plastic trim removal kit
  • Jack and jack stands
  • Isopropyl alcohol

Fitting steps

  1. Dry-fit the diffuser

    Place the diffuser under the rear bumper of your Ford Focus MK4 (2019-2021) and check the alignment with the exhaust outlets.

  2. Remove the original part

    Remove the screws and clips under the bumper, then unclip the original skirt or diffuser.

  3. Clean and degrease

    Wash the fitting area, then degrease it with isopropyl alcohol. Let it dry completely.

  4. Stick on the diffuser

    Dry-fit the diffuser, peel the film off the double-sided tape, then press firmly for 30 seconds over the whole surface.

  5. Check the result

    Check the alignment with the exhaust outlets and the clearance from the ground.

  • Put the vehicle on jack stands or a lift: never work under a car held up only by the jack.
  • Let the exhaust cool down before working near it.
  • Fit above 59 °F (15 °C) and avoid washing for 24 h: the adhesive reaches full strength after that time.
